l cconipanying drawings, Figure esen ing a vertical section, Fig, 2 a side i and Fig, 3 a plan, of the apparatus adapted to hie burner or to each of a number of burners intended to be actuated by electric ity. Fig, l a part section of the lower par' oi the apparatus, with a slightinodilication in the arrangement of the valve.

The pipe 11, leading up to the burner B, is of soft iron, constituting the core oi an electroinagnet, and for that pn pose being surrounded by a coil, or" insulated "wire. Jhe lower end or the pipe A is screwed into socket, F, of non-magnetic material, such as brass. D is a permanent magnet, of horseshoe form, having; its polar extremities d cl forked, to receive the pipe A in the upper fork and the socket .1. in

the lower fork, so that A is polarized by induction from the magnet D, In the socket F is formed a widened cavity, in which is placed a soft-iron valve, E, which, being" attracted toward the end of the pipe A, is caused to seat upward against a perforated nipple, a, of ivory or vulcanite, and so to close the passage through a, thereby cutting off the supply of gas to the burner The valve ll lies suflicicntl y above the for ed lower pole of the magnet l) to cause said valve to have a tendency to rise should said lower pole at an 3* time have a repulsirelyna-gnetic relation to it.

insulated conducting-Wires lead to and jroin the coil 0, and also to and from two platinum nibs, ll ll, situated a little above the oriliec of the burnt with their points at a suitable distance apart to permit an electrical spark to pass from the one to the other. Connections are made from the vvires G to these of insulating material, such as vulcanite, which is secured to the burner-pipe by a nut, i.

W hen it is desired to kindle the gas-flame, electrical currents are sent along the conductin g-rvires G G from any convenient source of electricity, or from a condenser or inductor, the current transmitted through the coil G being of such sign as to neutralize and overcome the magnetism induc by the magnet D on the hipe it, and valve 3J1. valve being thus no longer attracted by A, or being: rcpclied from it, drops avvay from the nipple a, partly by gravity and partly front the attract ivc force oi the lower pole of magnet l) and rests on projecting ribs f, whereupon gas rlows from the supply-pipe 1 past the valve IE, and through the nipple a to the bur and issuing therefrom ignited by the spark passing between the nibs ll:

piece, I.

'jlhe electrical current may then be intei'initted until 'it is desired to extinguish the light, in hich case an electrical current is transmitted by the ivircs through the coil (3 ct such. sign as to restore to the lower end of A. attractive force sufficient to draw to it the valve E, which thereupon rises and closes the gaspassage Lihe distance between the ribs f and the lower end of the core A is such that when the valve E rests upon said ribs it will not be close enough to said core to be attracted thereby, as the effect of the induction of magnet D in said core; but the attractive force of said core must be re-enforced by the electro-magnetism induced by the electric current in coil F in the proper direction. The entire attractive power of the core Ais then assisted by the repulsive force of the lower pole of the permanent magnet I), which, of course, begins to act upon the valve E immediately an attractive force begins to act upon said valve from the opposite pole. These combined forces give the valve a very prompt action. In order to in-' sure its prompt movement, it is desirable that the valve should be as light as possible. Were it not for' the attraction of the lower pole of the magnet for the valve, it would, of course, have to be heavy enough to resist displacement and elevation by the current of gas issu-' ing from pipe F; but owing to the effect of said lower pole in holding the valve to its seat, I am enabled to make it much lighter than would otherwise be the case.

According to the modification shown in Fig. 4, the supply of gas is by a lateral branch, K, and an adjustable screw, 0, forms the stop on which the valve E rests when the gas-passage through a is opened.

Instead of employing separate conductingwires G G for the coil 0 and, the nibs H H, respectively, both the coil and the nibs may be connected in one circuit, either parallel or continuous; but in the case of parallel counection the coil must be such as to presentconsiderable resistance to the electrical current, so as to insure the production of a spark between the nibs H H.

The transmission, interruption, and reversal of the electrical currents at the sending-station maybe efl'ected by any known key or apparatus ordinarily used for telegraphic purposes; and when the kindling or extinction of the light is used for signaling, the key apparatus at the sending-station may be worked as a relay, translating signals, such as those of the Morse or other known codes, into flashes or obscurations of the light of varying duration, as may be readily understood.

Sometimes for signaling purposes it is of advantage that the light should never be quite extinguished, but only at intervals obscured. In that case we provide a small by-pass orificeprovided with a stop-cock, which allows a small quantity of gas to pass the nipple a when its perforations are closed by the valve E, this small supply being just sufficient to keep the gas kindled, but not with a luminous flame.-

The gas supplied to burners fitted with our apparatus may be conducted to them by pipes, in the ordinary way; or, in cases where it is inconvenient to conduct pipes to them-as, for example, when they are on 1i ght-ships at seathe gas may be supplied from portable reservoirs, into which it is compressed, and whence it is led to the burners through suitable governors, as described in Pintschs patent of 22d May, 187 7. p

Having thus described the nature'bf our invention, 'Zmd the best means we know of carrying it on in practice, we claim 1. In an electrical gas lighting and extinguishing apparatus, an electro magnet the soft-iron hollow core of which forms part of the gas-passage, a permanent magnet having one of its poles connected to one end of said core, a soft-iron valve adapted to close the passage in said core, and arranged between the other end thereof and the other pole of the permanent magnet, substantially as and for the purpose set forth.-

2. The combination of the electro-magnet having the soft-iron hollow core A, the unmagnetic valve supporting pipesection F, the

permanent magnet D, having one of its poles in contact with the upper end of said hollow core, and its other lying under-the valve-seat, and the soft-iron valve E, substantially as described.

In testimony whereof We have signed our names to this specification, in the presence of two subscribingwitnesses, this 6th day ofJune,
